I want to take backup of my website which is hosted on godaddy.
I used pscp command from my windows dos and try to download whole public_html folder.
my command is :
pscp -r user#host:public_html/ d:\sites\;
Files are downloading properly and folders also. But the issue is public_html and other subfolders has two folder like "./" and "../". Due to these two folders my copy is getting failed and I am getting
"security violation: remote host attempted to write to " a '.' or '..' path!"error.
Hope any one can help for this.
Note : I have only ssh access and have to download it from ssh commands itself.
Appending a star to the source should fix it, e.g.
pscp -r user#host:public_html/* d:\sites\;
Also you can do same thing by not adding '/' at the end of your source path.
For eg.
pscp -r user#host:public_html d:\sites
Above command will create public_html directory if not exists at your destination (i.e. d:\sites).
Simply we can say using above command we can make a as it is clone of public_html at d:\sites.
One important thing: You need to define the port number over here "-P 22".
pscp -r -P 22 user#host:public_html/* D:\sites
In my case, it works when I use port number 22 with the above script.

this might be a dumb question, but I checked everywhere and there's no direct answer to it.
I set up both SSH keys successfully and I can connect to my instance via terminal, but when I do "ls", it doesn't show me any output. I am using iTerm2 with zsh on my Mac but I don't think this is an issue.
Can anybody give me a hint? Thanks!
When you access a VM through SSH, your working directory is the home directory of the user specified with the SSH command, i.e. /home/username. In case you access as root, the working directory will be /root.
You can check it through the command pwd
If it is a brand new machine, it is normal that the output of 'ls' is empty since in your home directory no file matches the filters of 'ls' with no parameters. The reason is that 'ls' doesn't show filenames starting with a dot ('.') because in the Linux convention they are hidden unless you run ls -al.
You can try again with $ ls -al and you will be able to see hidden files and directories as well.
On the other hand you can create as well first an empty file and then running again 'ls':
$ touch file
$ ls
I'm trying to access a server using Filezilla and was told I needed to use authentication with public/private keys. I created the keys using the Terminal, but cannot find them on my computer.
This is where the key is located:
(/Users/ed/.ssh/id_rsa)
I checked in my home directory, but the folder .ssh is nowhere to be found. Is there a secret place .ssh folder is stored and how can I access it?
My Mac runs on OS X ElCaptain. I would really appreciate any help.
Files and folders starting with a period (.ssh) are hidden by default. To find private/public key, run this commands:
ls -a
In your case, run this commands to find the ssh keys:
cd ~/.ssh
then:
ls -a
Now you should see the keys like this:
. .. id_rsa id_rsa.pub
If the keys are not there then definitely you need to create the key by ssh-keygen command.
(MacOS) I my case, .ssh folder was hidden so I went to folder route (example /Users/syed.dastagir)and pressed Command + Shift + . (full stop/period) and it showed me .ssh folder.
When you no longer want to see the hidden folders just press Command + Shift + . again.
If using Finder, I used defaults
Terminal
write com.apple.Finder AppleShowAllFiles true [Press Return]
killall Finder
Then I was able to see .ssh directory in Finder at
/Users/MYUSERNAME/.ssh
when referencing the private key name, when setting up the config file for GitHub for example ( https://docs.github.com/en/authentication/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent#adding-your-ssh-key-to-the-ssh-agent ), I thought I needed an id with number, i.e 'id_43248390', however I just needed to reference 'id_rsa'.
This is incase any gets blocked similarly.
I am trying to copy from remote ubuntu machine to local windows:
pscp name#example.com:/home/www/file c:\xampp\htdocs
Instead of getting a copy on local i get c:xampphtdocs file created on a remote.
I was refering to this http://the.earth.li/~sgtatham/putty/0.60/htmldoc/Chapter5.html
What am i doing wrong?
Thanks.
pscp doesn't handle well the colons in your path and it thinks that c is remote server. If you use relative path like this, it should work for you:
c:\
pscp name#example.com:/home/www/file \xampp\htdocs
For instance, I have tried this (notice sources is remote):
scp root#$node:/sourcepath/sourcefile.log /destinationpath/destinationfile.log
The other option is to rename the file afterwards, but would be more convenient to do it on the fly while the data is downloaded via scp, therein my question. Thanks.
Maybe without scp:
ssh yourserver "cat >tmpfile && mv tmpfile datafile" <datafile
This command copies the "datafile" file to a remote server under the name "tmpfile".
Only after successful copy renames the temporary file "tmpfile" to the right name "datafile" on remote host.
If copying was not successful, the remote host will be only a temporary file.
Thus, you are protected from getting no full "datafile" file.
Sorry for my English.
I have setup an NFS file share between two CentOS 6, 64 machines. On the server the folder being shared was originally owned by the root user. On the client it turned up as being owned by nfsnobody. When I tried to write to the folder from the client I got a permissions error. So I changed the folder ownership on the server to nfsnobody and chmod'd it to 777. However, still no joy - I continue to get a permissions error. Clearly, there is more to this. I would be much obliged to any Linux gurus out there (I personally wouldn't merit being called anything more than a newbie) who might be able to help fix this issue.
Edit - I should have mentioned that trying to write to the shared folder from the client actually manages to create a file entry. However, the file size is 0 and the permissions error is reported.
The issue here is to do with the entry in /etc/exports. It should read
folder ip(rw,**all_squash**,sync,no_subtree_check)
I had missed the all_squash bit. That apart, make sure that the folder on the server is owned by nfsnobody. On my setup both my client and server nfsnobodies ended up with a user id if 65534. However, it is well worth checking this (/etc/groups) or else... .
Here are a couple of useful references
How to setup an NFS SErver
NFS on CentOS
For the benefit of anyone looking to setup an NFS server I give below what worked for me on my CentOS 6 64bit machines.
SERVER
yum install nfs-utils nfs-utils-lib - install NFS
rpm -q nfs-utils - check the install
/etc/init.d/rpcbind start
chkconfig --levels 235 nfs on
/etc/init.d/nfs start
chkconfig --level 35 rpcbind on
With this done you should create the folder you want to share
mkdir folder
chown 65534:65534 folder
chmod 755 folder
Now define the folder to be shared/exported. Use your favorite text editor (vi or whatever) to
open/create /etc/exports
folder clientIP (rw,all_squash,sync,no_subtree_check)
Client
Install, check, bind and start as above
mount -t nfs serverIP:folder clientFolderLocation
If all goes well you should now be able to write a little script on your client
<?php
$file = $_SERVER['DOCUMENT_ROOT']."/../nfsfolder/test.txt";
file_put_contents($file,'Hello world of NFS!');
?>
browse to it and find that test.txt now exists on the server with the content "Hello world of NFS". In the example I have placed my mounted drive one level before document_root.
